Who it is for
Homeowners and renters checking whether furniture fits before buying or moving.
Overview
HZplan converts a photo of a floor plan, or a written set of dimensions, into a structured and editable plan. The model it builds contains storeys, walls, openings, rooms, and objects, each of which can be inspected or changed.
Plans and room topology render inside ChatGPT, so a change can be seen without exporting. Geometry can be rescaled, floor-plan images imported, and private SVG illustrations created. Deleting private content is a stated function.
The example prompts are measurement questions: placing a 1.5 metre sofa facing a window, or checking whether a bed of 2 by 2.4 metres fits a given bedroom.
Homeowners and renters checking whether furniture fits before buying or moving.
It keeps a structured model of the building instead of an image, so dimensions can be queried and edited.
Availability
HZplan is listed in the ChatGPT apps directory only. Artem Goncharov has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.

This is an independent catalogue entry compiled by Node8 from HZplan's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with Artem Goncharov, and inclusion here is not an endorsement.
Node8 builds MCP servers end to end: deciding which tools are worth exposing, the authentication and permission model, the review submissions, and the onboarding that gets them used. One server serves ChatGPT, Claude, and Microsoft Copilot.
